LP28400A - 2 cell Li-ion Battery Charge

General Description

The LP28400A is a complete constant-current/ constant voltage switching charger for multi cell lithium-ion batteries.

Boost+Linear charger work with a USB 2.0 compliant power IC assuring 2 cell LiIon battery charging.

When the battery voltage is low, the charger works in linear operation mode.

Key Features

  • include charge current monitor, under voltage lockout, automatic recharge and a status pin to indicate charge termination. Order Information LP28400A.
  • F: Pb-Free Package Type SP: ESOP8 QV: QFN-16 Output voltage A: 8.4V B: 8.7V C: 8.8V.

Preliminary Datasheet LP28400A 2 cell Li-ion Battery Charge from 3V~12V General Description The LP28400A is a complete constant-current/ constant voltage switching charger for multi cell lithium-ion batteries. Boost+Linear charger work with a USB 2.0 compliant power IC assuring 2 cell LiIon battery charging. When the battery voltage is low, the charger works in linear operation mode. Along with the charging the battery voltage is higher the charger will transfer to Boost operation mode smoothly. When the battery voltage <6V, switch to wake-up current charging. Other features include charge current monitor, under voltage lockout, automatic recharge and a status pin to indicate charge termination.
